These are the curves for a "kinkless" tetrode - a beam tube.
If it didn't have the beam plates, the curves would have a kink, a big ripple, just after the point where they start to flatten out, somewhere around the vertical "100V" line..
This makes the tube rather non linear through a mjor part of it's anode current swing, and hence unsuitable for good audio.
